RADIATOR.

Specification of Letters Patent.

Patented Dec. 12, 1911.

Application filed April 12, 1907. Serial No. 367,757.

T 0 all whom it may concern:

Be it known that we, ALBERT BAERENKLAU, JOHN L. FLANAGAN, and J AMESLLOYD WIN- TERS, citizens of the United States of America, and residentsof the city of New York, county of Kings, State of New York, haveinvented certain new and useful Improvements in Radiators, of which thefollowing is a specification.

This invention relates to steam heating systems and has for its objectto provide an improved radiator for use in such systems.

Our invention consists in the particular construction of a steamradiator, wherein means are provided for causing the condensation waterto accumulate, and means for heating the thus isolated. or local body ofwater by steam. The advantage of such a radiator is this, that a mildsoothing heat is obtained similar to the heat produced by a waterradiator pure and simple, but that all the apparatus needed in a waterheating system is eliminated and a simple steam heating system isinstalled.

Our invention also provides means whereby the said radiator may be usedas a steam radiator only, and provision is made for controlling andregulating the radiator.

Hence, our invention comprises such elements and features ofconstructionas will hereinafter more fully appear, reference being hadto the accompanying drawings in which our invention is embodied in aconcrete form; but as changes may occur, we reserve the right to allsuch changes as come within the legitimate scope of the invention andthe claims.

In the said drawings :Figure 1 shows a steam heating system embodyingour invention, partly in section, with some elements in diagrammaticform. Fig. 2 is a cross section on line 22 of Fig. 1. Fig. 3 is asectional view of a portion of a radiator provided with a regulatingvalve embodying our invention. Fig. 4 is a similar View showing amodification.

The reference numeral 1 designates a boiler of conventional type'forgenerating steam, 2 indicates the main header from which the pipes 3lead to the different radiators 4, which are constructed as usual inso-called loops as 5. Each pipe is provided with the usual valve 6 andeach radiator with the usual air valve 7 In the loop nearest theconnecting pipe 3 we provide a separate heating chamber 8 by means ofthe partition 9. This heating chamber forms a passage and space for thesteam, which is employed to heat the water, which will be contained inthe radiator proper on the other side of said partition, whichpreferably is corrugated as shown in order to obtain as much heatingsurface adj acent the water as possible. To further increase the heatingsurface and to heat the local body of water at the bottom, a tube 14: isinserted in the partition. The heating chamber communicates with theinlet valve 6 by the connection 13, and with the interior of theradiator by the narrow passage 10 at the top. At the bottom a by pass 11is provided which is controlled by the valve 12. The tube 14 is closedby the cap 15.

In order to avoid repetition one of the radiators in the system is shownin diagrammatic form, but the radiators are all constructed alike.

When it is desired to use this radiator as an ordinary steam radiator,the operation is as follows: The by-pass valve 12 is fully opened andthe steam passes into the radiator both through this by-pass and by wayof the heating chamber and passage 10, and also fills the tube 14:. Asthe steam passes in, the air is driven out' through the air valve asusual, and the radiator now operates as an ordinary steam radiator, thecondensation water passing out through the by-pass and from the tubeback to the boiler.

Then it is desirable to utilize the radiator as a'water radiator, orrather, to obtain a mild steady heat, such as given off by waterradiators the bypass valve 12 is closed, thus leaving the passage 10 asthe only communication between the heating chamber and the interior ofthe radiator. The condensation water will now begin to accumulate and indue time it will stand as high as the partition, while it is beingheated by steam which constantly is supplied through the heating chamberand passage 10, and by the steam in the tube 14, which together with thecorrugations on the partition afford suflicient heating surface. Theheat now given off by the radiator is mild and exactly like the heatobtained from a water radiator, and entirely unlike the intense heatproduced by a steam radiator, and whatever overflow there is, as byexpansion or condensation of the steam on top of the water, drips intothe heating chamber and back to the boiler. From this it will beunderstood that by incorporating our improved radiator in a steamheating system, we obtain the advantages of a water heating system. Andon the other hand, the disadvantages of the last named system areeliminated. Some of these disadvantages may well be set forth here inorder to fully understand the importance of our invention. A waterheatmg system requires two-pipe work and larger piping and radiatorsthan a steam heating system. An expansion tank is also needed. Steamheating systems are connected up in the manner known as onepipe work,smaller radiators may be used and no expansion tank is required.Moreover, as we heat the water in the radiator by steam within the samewe are able to heat the water quickly and to maintain a highertemperature with a smaller radiator than is now possible with waterradiators. Another important feature of our construc tion resides in thefact that steam is intro duced on the top of the water whereby the socalled hammering or noise produced when the water gets boiling isimpossible in our radiator. In ordinary water heating systems this noiseis very frequent and very objectionable.

If it is desired to use steam only, the bypass is opened and the waterflows out. In cases where a two-pipe steam heating system is alreadyinstalled, the tube 14 will be given a pitch toward and connected to thedischarge pipe. The discharge connection is shown in dotted lines as itis not necessary in connection with our invention.

WVe will now describe the means for regulating or controlling theradiator by cutting off heating surface (see Figs. 3 and 4). These meansare shown separated as the radiator 4 may or may not be provided withthem. Outside the loop containing the partition 9 is added another loop,designated by 20, and communicating with said chamher by the passages 21and 29. The interior of said loop 20 is closed at the bottom by the wall22 in which is inserted the pipe 23 having the vertical slot 24. Thispipe forms the outer casing of the valve 25 which is in the form of atube open at the bottom and having the spiral slot 26, ending at the topin the aperture 27. The valve 25 is rotated by means of the handwheel28.

In Fig. 3 the valve is shown as being shut, that is, the steam in thisinstance enters the radiator by passing up through the valve and throughthe passages 21 and 10, the passages 29 being closed by the condensationwater which stands at the level of the aperture 27. Consequently thesteam or heating room of the radiator is very small and less heat willbe radiated. If it is desired to increase the temperature, the valvewill be turned until a certain portion of the spiral slot registers withthe vertical slot in the valve casing, which will be at a lower levelthan at 27 and consequently the height of the condensation water willdecrease and more steam room he obtained, hence the temperatnre willrise. If the radiator is filled with water and is to remain filled asabove described, the by-pass is closed and the regulation then affectsthe space outside the partition only, that is, more or less steam spacein the loop 20 may be obtained for keeping the water in the radiatorhot. The water in the radiator will stand as high as the partitlon, butoutside the latter, the condensation water may stand at a differentheight.

In 1g. 4 is shown a modified valve construction in which the valve 30carries at its bot-tom another valve 31 which opens or closes the inletpipe 13, and the steam enters the valve 30 through openings 32. Thevalve 80 is in this instance threaded into the wall 22 and as it isrotated it is simultaneously given a vertical motion, in such a mannerthat as the condensation water is allowed to rise, the inlet valve ismoved nearer 1ts seat, whereby less steam is supplied the radiator. Inall other respects this construction operates like the one shown in Fig.2?). In this figure the reference numeral 40 ind cates the point atwhich the two slots reg1ster, and at which level the condensation waterwill stand. Steam will of course enter the radiator through the aperturethus created, as well as at the top of the valve.

The construction of the radiator provided by our invention and theoperation of the same 18 thought to be clear from the foregoing, and itwill be understood, that the advantage of water heat, to use this commonexpression, is incorporated and obtained 1n a steam heating system.This, to the best of our knowledge, it has not been possible toaccomplish before.

The radiators are all fed with steam from a common source, but one ormore of them operated at will so as to contain local bodies of water,which do not circulate, but which are heated by the steam. By a localbody of water we mean the water contained within the radiator asdistinguished from the water in a water heating system, in which thewater circulates through the whole system.

W hat we claim is 1. In a steam radiator the combination of a verticalpartition, a heating chamber formed to the one side thereof andcommunicating with the interior of the said radiator at the top, a valvechamber formed adjacent the said heating chamber and communicatingtherewith, a valve in said valve chamber comprising a slotted sleeve, avalve body in said sleeve and provided with a spiral slot adapted tocooperate with the aforesaid slot to cause the condensation Water toaccumulate at Will and means for supplying steam to the bottom of thesaid valve chamber.
